Rodents inspire dentistry
Rodents inspire dentistry
Researchers discover an iron-containing material in the outer enamel of rodent teeth that could also make human teeth more resistant   Rodents such as beavers, nutrias (coypu) , squirrels and rats have particularly strong, elongated front teeth that grow continuously over the course of their lives. Using state-of-the-art imaging techniques, researchers at the Max Planck Institute for Solid State Research in Stuttgart have now elucidated the tooth structure of various rodent species at the nanometre scale.

Perturbations simplify the study of 'super photons'
Perturbations simplify the study of ’super photons’
A study by the University of Bonn gives novel insight into properties which are often difficult to observe Thousands of particles of light can merge into a type of "super photon" under suitable conditions. Physicists call such a state a photon Bose-Einstein condensate. Researchers at the University of Bonn have now shown that this exotic quantum state obeys a fundamental theorem of physics.

TU Graz Revolutionises Simulation of Metal-Organic Frameworks (MOFs)
TU Graz Revolutionises Simulation of Metal-Organic Frameworks (MOFs)
Due to the complex structures of microporous crystals known as MOFs, reliable simulations of their properties have been difficult until now. Machine learning provides the solution. Hydrogen storage, heat conduction, gas storage, CO2 and water sequestration - metal-organic frameworks (MOFs) have extraordinary properties due to their unique structure in the form of microporous crystals, which have a very large surface area despite their small size.

Exotic black holes could be a byproduct of dark matter
In the first quintillionth of a second, the universe may have sprouted microscopic black holes with enormous amounts of nuclear charge, MIT physicists propose. For every kilogram of matter that we can see - from the computer on your desk to distant stars and galaxies - there are 5 kilograms of invisible matter that suffuse our surroundings.

Scientists detect slowest-spinning radio emitting neutron star ever recorded
Artist's depiction of CSIRO's ASKAP radio telescope with two versions of the mysterious celestial object: neutron star or white dwarf Most collapsed stars rotate faster than once per second. This one takes nearly an hour. Scientists have detected what they believe to be a neutron star spinning at an unprecedentedly slow rate -slower than any of the more than 3,000 radio emitting neutron stars measured to date.

Paving the Way for Hydrogen from Algae Enzymes
Paving the Way for Hydrogen from Algae Enzymes
A research team from Bochum has identified a crucial detail that's essential for the production of hydrogen using biocatalysts. Under certain conditions, some algae are able to produce hydrogen - a much sought-after green energy source. Its production takes place in the unique catalytic center of the unicellular algae and is only possible if certain cofactors of the relevant proteins are present.

A Better Model for Converting Carbon Dioxide into Fuels and Products
Some parts of the world have been so successful in making inexpensive renewable electricity that we occasionally have too much of it. One possible use for that low-cost energy: Converting carbon dioxide into fuel and other products using a device called a membrane-electrode assembly. A team of scientists from Lawrence Berkeley National Laboratory ÜBerkeley Lab) and the University of California Berkeley have developed a new approach to understanding this promising technology via physics modeling.

A Cleaner Way to Produce Ammonia
Ammonia is the starting point for the fertilizers that have secured the world's food supply for the last century. It's also a main component of cleaning products, and is even considered as a future carbon-free replacement for fossil fuels in vehicles. But synthesizing ammonia from molecular nitrogen is an energy-intensive industrial process, due to the high temperatures and pressures at which the standard reaction proceeds.
